as we all know the most tire used in gt6 are comfort soft, 99.9% of the lobbies have that restriction of tires. Today I was looking for some information about the type of tires they use in the D1 competition after viewing some video the tires seemed to me semi-slick. so look for information about one of the best drivers in the competition and found the type of tire used. http://www.madmike.co.nz/cars this is the link to the specs of the car (TYRES: Nitto NT05 235/40R18 front 265/35R18 rear) if you do not want to click on the link http://www.nittotire.com/Tire/Street/nt05 and this is the link of the tire on the official page in my opinion looks more semi-slick tire than a road tire.. that in the types of tires in gt6 would are sports (hard,med,soft) what you like. what you think guys?
